I found I needed this part after a squeaky brake forced me to change the brake pads on my front wheels. It turned out that only one of the four pads was worn down to the metal and the rest was fine. I installed new pads but found that one of them was very difficult to insert into the bracket and it jammed and shifted as a result. Of course, this is where the worn block was (it was also difficult to remove). Cardone's caliper bracket was the perfect replacement - all dimensions and finishes matched the factory part so this replacement was a no-brainer. No more wrinkling or warping, just smooth running of the pads in lubricated guides (silicone lube is also included) I wish I had known I had heard this grinding before, so the warped rotor also had to be replaced. And yes, by Revain again. Only $50 but it was worth it!
